Electronic keyboard instrument developed by Ivan Eremeeff in Philadelphia, Pennsylvania, in 1932; it was the smaller and better known of two instruments based on the same principles that Eremeeff built in that year. Rotating electromagnetic tone wheels generated the sounds. The keyboard (three and a half octaves) and the bench on which the player sat formed part of an electrical circuit; when one of the stationary, touch-plate keys was fingered, an electrical contact was made through the performer’s body with the metal top of the bench. In addition to pedals governing volume and tremolo there was also a decay control. The Gnome was designed for home use and could be connected to the amplifier and loudspeaker of a domestic radio set....
